SALINE-OPERATED ELECTRIC CIRCUII IT AND ELECTRORESPONSIVE APPARATUS.

Specification of Letters Patent.

Patented Jan. 6, 1920.

Application filed December 29, 1916. Serial No. 139,698.

To all whom it may concern:

Be it known that I, HENRY WYGODSKY, a subject of the Emperor of Russia,and a resident of New York, borough and county of Bronx, and State ofNew York, have invented certain new and useful Improvements inSaline-Operated Electric Circuits and Electroresponsive Apparatus, ofwhich the following is a specification.

My invention relates to the operation of mechanical devices by means ofan electromagnet arranged in a normally open electrical circuit adaptedto be closed by a saline fluid, for instance urine, the terminals ofwhich circuit are in permanently spaced relationship, and the mainobject thereof is to provide such apparatus of a simple form ofconstruction and installation adapted to perform a mechanical operationin the presence of a saline fluid.

My invention is fully described in the following specification, of whichthe accompanying drawings form a part, in which like characters refer tolike parts in each of the views, and in which Figure 1 is a View, partlyin section, of the adaptation of my invention to the flushtank of aurinal;

Fig. 2 is an enlarged section taken on the line 22 of Fig. 1;

Fig. 3 'is a bottom plan view ofthe attachment shown in Figs. 1 and 2,to the bowl of the urinal; and

Fig. 4 is a diagrammatic view of an actuated by the saline fluid.

Referring to Figs. 1, 2 and 3, the bowl 5 of a urinal is provided with adrain opening 6 and with a flush-pipe 7 leading from a water tank 8having the usual or any desired type of valve therein operable by meansof a lever 9 for flushing the urinal, said lever being actuated by anelectromagnet 10 arranged in a normally open ci'rcuit through conductors11 and 12, through a relay 14, and, by means of a supplemental normallyopen circuit of low voltage, through the source of energy 13, to actuatethe valve lever 9 by means of the electromagnet.

Arranged in the drain opening 6 is a spider 15 having a flanged ring 16at its top of conductivematerial and, in turn, supporting an insulatingdisk 17 having a threaded bore therein for the reception of a screwthreaded post 18 having a convex disk 19 at its upper end of conductivematerial, the ring 16 and disk 19 serving as terminals in thesupplemental circuit and being in permanently spaced relationship thegap between which may be narrowed or widened at will by the rotation ofthe post 18 in the insulator 17, and it will be noted that the disk 19is arranged over the ring 16 in such manner as to insure the passage ofurine from said disk 19 to said ring when the urinal is being used.

This saline fluid in spanning the gap closes the circuit through theelectro-magnet 10 and the flushing valve lever is actuated to flush thebowl 5 and, inasmuch as the saline property of theurine is weakened bythe flushing water and its superior electrical conductivity overordinarywater is thus overcome and the circuit is again interrupted between theterminals 19 and 16, the

electro-magnet deenergized, and the valve' sulate said plates from eachother and shown at 22, a suitable binding 23 holding the parts together.

The terminals 20 and 21 are connected with electrical conductors 24 and25 led through a source of electrical energy 26 and through a buzzer 27and, upon a saline discharge by the baby, beneath which the terminalplates and insulator are arranged, the fluid saturates the absorbentinsulator and the terminals are electrically'connected through saidsaline fluidand the buzzer 27 is actuated to notify a nurse that changesin the clothing of child and bed should be made.

Inasmuch as I have knowledge of electrical circuits having terminalsmovable toward each other by the influx of water in a receptacle,attention is particularly drawn to the fact that my juxtaposed ter-While I have. shown tWo adaptations of my invention,'it Will be obviousthat many other uses n'light be conceived, and I reserve the right tomake structural changes to adapt the invention to such other uses.

Having fully described my invention, What I claim as new, and desire tosecure by Letters Patent, is

The combination With a urinal and a flushing device; of anelectro-magnet in operative connection With said device, a

source of electrical energy, a conductive ring arranged in said urinal,an insulator 1 said source of energy. said disk and ring 20 beingadapted to beelectrically connected by a saline fluid interposedtherebetvveen and electrically disconnected by the substitution of.Water for said saline fluid.

HENRY WYGODSKY.
